Assembly service

Phil (korben69),

please let us know what you want to do about the assembly service requested from several members.

If you think that you cannot provide the service, please send me back all the items I sent you on April.
I don't own much free time, but the members have been waiting for 6 months, so I will try to provide this service myself.

Please, let us know as soon as possible.

Thanks
Andrea

Hi

I received answer form some members about the Assembly Service.
I'm checking their orders according to the Order Form and Andreas specs.

I've got no news from : thostenlarsen, zenelectro and JethroTull.
I've got their parts aside but don't know what to do with them.

Triodehunter asked me to send his crytals and PCBs back to Andrea. Waiting for delivery address.
I'm waiting for Lindamar opinion to send or not his order back to Andrea.
Maybe I'll ship his parts with Triodehunters and split shipping costs.

What about 90.3168 & 98.3040 technical issues and recommended values ?

If some members decide to cancel their Assembly Service order, just push me mail.
I'm very sorry for this waste of time.

Regards

Phil

I have not yet solved the issue about 90/98 MHz, next days I'll try the last opportunity replacing the J310 with the BF862 (higher transconductance).

If they will not work anyway, I have almost ready the Driscoll emitter coupled oscillator (to be used with SC-Cut crystals), that should be work fine also with harmonic AT-cut crystals. I'm ready to order the PCB prototype.

Andrea that would be a very great news.

Any idea if we have met the minumum ordering quantity for 2nd batch AT and SC yet?

AT-cut 16.9344 MHz (16)
AT-cut 22.2792 MHz (13)
AT-cut 24.5760 MHz (11)
AT-cut 25.0000 MHz (16)

For the following frequencies, the MOQ was not reached:
SC-cut 90.3168 MHz (2), MOQ 15 pcs
SC-cut 98.3040 MHz (1), MOQ 15 pcs
AT-cut 6.1440 MHz (4), MOQ 15 pcs
AT-cut 11.2896 MHz (1), MOQ 10 pcs
AT-cut 12.2880 MHz (3), MOQ 10 pcs
AT-cut 27.0000 MHz (1), MOQ 10 pcs
AT-cut 45.1584 MHz (7), MOQ 10 pcs
AT-cut 49.1520 MHz (6), MOQ 10 pcs
AT-cut 90.3168 MHz (1), MOQ 15 pcs
AT-cut 98.3040 MHz (1), MOQ 15 pcs

Please, keep in mind that TWTMC-C (Clapp oscillator) is not suitable for SC-cut crystals. I'm developing the TWTMC-D (emitter coupled Driscoll oscillator) to be used with SC-cut crystals; next days I will order the PCB prototype.
Also, remember that SC-cut crystals need an oven to work correctly; I'm developing the TWTMC-OVN (see previous posts), I will order the PCB prototype soon.

BTW, I have to get SC-cut Crystals (MOQ for each frequency) to test the Driscoll oscillator, so, please, send me the filled order form as soon as possible.
As I said previously, the Driscoll oscillator could be used also for harmonic AT-cut crystals (from 33.8688 MHz up to 98.304 MHz).

AT-cut 25.0000 MHz (16)

For the following frequencies, the MOQ was not reached:
SC-cut 90.3168 MHz (2), MOQ 15 pcs
SC-cut 98.3040 MHz (1), MOQ 15 pcs
AT-cut 6.1440 MHz (4), MOQ 15 pcs

AT-cut 90.3168 MHz (1), MOQ 15 pcs
AT-cut 98.3040 MHz (1), MOQ 15 pcs

Please, keep in mind that TWTMC-C (Clapp oscillator) is not suitable for SC-cut crystals. I'm developing the TWTMC-D (emitter coupled Driscoll oscillator) to be used with SC-cut crystals; next days I will order the PCB prototype.
Also, remember that SC-cut crystals need an oven to work correctly; I'm developing the TWTMC-OVN (see previous posts), I will order the PCB prototype soon.

BTW, I have to get SC-cut Crystals (MOQ for each frequency) to test the Driscoll oscillator, so, please, send me the filled order form as soon as possible.
As I said previously, the Driscoll oscillator could be used also for harmonic AT-cut crystals (from 33.8688 MHz up to 98.304 MHz).

Hi Andrea, if the MOQ for the AT's is not reached and you are close to getting the SC boards ready then I'd like to jump ship to the SC camp.

Some guidelines

Hello Andrea,

It was just pure luck I went in here checking the status of this thread as it has been moving at slow pace. I have been out of my audio hobby for a while now.

Please try to:

1. Make a summary of this thread on the first page of the tread with the most important information and links to relevant pages. Like now for me, looking for the order form, where is it? What has been developed for for a certain type of crystal, etc ?

2. Send a private message to everyone on the interest list when it's time for an order (including info about where to find the order form).

😉
